FRUIT-JAR.

SPECIFICATION forming parbof Letters Patent No. 320,580, dated June 23, 1885.

Application filed March 16, 1895. (No model.)

To a/ whom, it may concern,.-

Be it known that I, CARLTON NEWMAN, of the city and county of San Francisco, State of California, have invented an Improvement in FruitJars; and I hereby declare the following to be a full, clear, and exact description ofthe same.

My invention relates to the class of fruit-` the lids ofjars.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1l is a perspective view of my fruit-jar. Fig. 2 is a vertical section ofthe upper portion of the same. Fig. 3 is a perspective view of the screw-band and bail.

A is the jar, and B its lid. Around the neck a ofthe jar are formed screw-threads a.

C is aband or ring internally threaded and adapted to t the threads a of the neck.

D is a bail the ends of which are rmly secured to the ring or band C. The center of the bail is bent downwardly and bears upon the center of lid B.

By screwing the ring C down the bail is carried down and caused to press on the center of the lid, thus tightening and binding it to its seat. The reverse movement of the ring relieves the lid. This central bearing which is brought upon the lid is better, in that it is more equal, than a bearing brought upon and throughout the circumference ofthe lid, as is usually done. There is no tendency to tip the lid by reason of anunequal pressure.

The fastening I have described is simpler and cheaper than the ordinary screw-sleeve, whose inwardly-turned top fiange binds on the edge of the lid, because in the manufacture of these sleeves great care must be taken to true their flanges to produce an even bear ing, and also more material is used in stamping out the sleeves than in forming rings, such as O. I ain aware that fastenings have been made by means of a centrally-bearing bail, the ends of which are bent to form hooks, engaging inclined lugs or planes on the :neck of the j ar; but the disadvantage of this fastening lies in the tendency of the bail (which is made of Wire) to bend or twist under the strain of setting it up, thereby disengaging its'hooks from the lugs. The resisting' power of the 'hooks is, moreover, small, both because oftheir size and the small bearing they find, and nally the bail is rather difficult to handle in setting it up. All these disadvantages are overcome by combining the bail with the screwband. I obtain the central pressure, and at the same time have a great resisting power, on account ofthe' large bearing and engaging surface of the ring or band to which the bail is attached. There is no tendency to slip, and the ring is easily grasped to set the bail to its position.

I am aware that fastenings are old in which a coil of wire encircles the threaded neck of the jar and to which bails are secured, the top centers of which bear upon the center of the cover or lid, whereby it is secured. I do not therefore claim such broadly, but confine myself to the solid annular band of metal internally threaded, which is adapted to t` the neck of the jar and to bind the bail upon the cover.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isy A fastening for binding the lid or cover of a jar to its seat, comprising the solid metal band or ring C, internally threaded and adapted to fit upon an externally-threaded neck of the jar, and the bail D, bearing on the center of the lid and having its ends secured to the met-al band or ring, substantially as herein described.

In witness whereof I have hereunto set lny hand.

CARLTON NEWMAN.
